Abstract
한국전자통신연구원은 2008 년 말에 발사될 예정인 통신해양기상위성에 탑재될 Ka 대역 안테나서브시스템을 개발하고 있다. Ka 대역 통신용 안테나 서브시스템은 위성체의 동,서 판넬에 각각 하나씩 구성되어 있다. 이를 추진하기 위하여 한국전자통신연구원은 현재 대한항공(주)과 공동으로 통신위성 안테나 서브시스템을 설계하고 있다. 본 논문은 이득 변화 등과 같은 안테나 서브시스템 성능 규격을 검증하기 위하여 Ka 대역 반사판 포인팅 에러 분석에 대하여 기술한다. 수행된 분석은 열변형에 의한 반사판 표면 변형 데이터 이며 이를Ticra로 빔패턴의 변화를 확인하였다.
